Achieved gain in activities for recreation and exercise

The Lightning Point Restoration Project focuses on protecting Bayou La Batre, one of the Gulf Coast’s few remaining working waterfronts. The community relies on fishing and seafood industries but faces increasing hazards from shoreline erosion, storm surge, hurricanes, and tropical storms. Past events such as Hurricane Katrina (2005) and oil spill (2010) caused major damage to infrastructure and livelihoods, highlighting the need for greater coastal resilience
Led by The Nature Conservancy and partners, the project combines engineered and natural approaches to safeguard the shoreline while supporting local livelihoods. Core activities include constructing approximately 1–1.5 miles of segmented breakwaters and jetties at the mouth of the Bayou La Batre River, and creating about 28–40 acres of coastal marsh, tidal creeks, and upland habitats using beneficially reused dredged material. Native planting and long-term monitoring support habitat performance and adaptive management.
These solutions aim to reduce wave energy, limit erosion, buffer storm surge, and maintain navigation, while restored marshes provide habitat for fish, shellfish, and birds. Designed to withstand nearly one foot of projected sea-level rise over the next 25 years, the project enhances shoreline protection, restores critical coastal habitats, and helps secure a resilient waterfront for Bayou La Batre’s economy and community (Ref. 1 - 4).

The Mediterranean climate in Lisbon, already characterised by low precipitation, has been further exacerbated by climate change. The city faces challenges related to biodiversity loss, urban loneliness, and climate anxiety (1). To address these issues, Lisbon's urban development plans have prioritised the re-naturalisation of urban spaces and the integration of ecological networks. Urban nature is now a central component of the city's Master Plan (2012) and other strategic agendas (1).
It is being developed by the LISGREEN project, which aims to enhance ecological connectivity and mitigate the effects of urban heat islands in Lisbon. By establishing nature-based solutions, it aims to restore forests within the city (1, 2, 3). This project encompasses different strategies, such as the RENATURA pilot project. It is a collaboration with the NGO URBEM and involves active public participation in tree planting and forest maintenance. This initiative aims to educate the community about nature, promote well-being, and mitigate extreme climate events (1), through the creation of urban forests.
The main strategy is to create fast forests using the Miyawaki method, which involves dense planting of native trees, removal of invasive plants, and intensive initial care. This approach accelerates the growth of natural forests within a short period, using native species and reducing the need for watering (1)
The first fast forest was developed in Parque Casal Vistoso within Bela Vista Park, within the Eastern Green Corridor of Lisbon. The park is being underutilised because of the lack of shade (1). Thus, this initiative encouraged volunteers to participate in tree planting and forest maintenance activities (3). The NbS intervention began with a 300m² experimental plot near the Vale da Montanha pedestrian bridge and has since expanded to a new 1,500m² plot on the opposite side of the bridge (2). Over 500 volunteers joined the effort, planting more than 3,800 trees (1)

The Thalangama wetlands are part of a network of wetland ecosystems around Colombo city that spread over 20 km2 and provide critical life support to the city. These ecosystems keep people safe from floods, cool the air, filter polluted water, provide food and medicines, and fight climate change (10). These wetlands have become an environmental protection area and a biodiversity hotspot in a rapidly urbanising environment, as they host an array of plants and animals, including the endangered fishing cat and otter (5, 10). In 2007, Thalangama Lake and its surroundings were declared an Environmental Protection Area (EPA) under the National Environmental Act (4, 5). This protected area covers approximately 118 hectares (4) and includes two man-made reservoirs: Thalangama Tank (11 ha) and Averihena Tank (3.2 ha), located just 300 meters apart (5). The area hosts floating and rooted plants, scrublands, and trees that provide habitat to up to 100 species of migratory, resident, and endemic birds throughout the year. In addition, the area supports 30 species of dragonflies, 12 species of reptiles, 10 species of mammals, and 15 species of freshwater fish (1, 4). Since the lakes and their surroundings were declared an EPA, only limited uses are permitted, such as traditional fishing and rice cultivation (4, 5). The lakes are also important for floodwater retention and have high scenic and aesthetic value, attracting many visitors, and scientific and educational activities (5, 13).
However, due to the area's rapid urbanisation, land values have increased significantly, leading to excessive landfilling and the reclamation of paddy lands for housing. This is compounded by the indiscriminate disposal of garbage and construction waste and the spread of invasive species (5). These challenges have also led to the engagement of surrounding communities in managing and maintaining it (11).

The environmental impact of golf has led to growing calls to make the sport more sustainable (1). Golf course maintenance often involves carbon-intensive fertilizers, frequent mowing, and, in some cases, the clearing of forests or trees that naturally absorb carbon dioxide to make room for expansive fairways (1). However, the Tournament Players Club (TPC) Michigan is working to create courses that benefit both golfers and the environment (2).
Fifteen years ago, the site was a neglected floodplain along the Rouge River, initially purchased by Henry Ford in 1915 and once littered with community waste and old motor parts from the Ford Motor Company (2-3). Today, it has been transformed into an 85.8-hectare course that supports a diverse range of wildlife, including birds, fish, foxes, and coyotes (2). Led by Jack Nicklaus, the restoration aimed to turn this former waste site into an eco-friendly course (2). With guidance from Audubon International, the course was converted into a wildlife sanctuary, becoming the world’s first golf course to receive the prestigious John James Audubon Environmental Steward Award for ecological restoration (2).
TPC Michigan features native Michigan plants, such as viburnums, which produce berries for wildlife, along with various native grasses (2). To prioritize environmental stewardship, the course managers have created buffer zones to protect natural habitats and conserve water by using coring methods to monitor soil moisture (2). Pesticide use is minimized; instead, staff monitor for signs of disease or pests and test the soil to determine the specific nutrients needed for the turf (2). The course’s links-style layout includes rolling fairways, tiered greens, and natural wetlands, with tee options ranging from 5.5 to 6.4 meters (4). By establishing a wildlife sanctuary, TPC Michigan offers golfers a unique experience that fosters a connection with nature (3).

Sri Lanka faces multiple natural hazards, including tropical storms, flash floods, and landslides. As the country's urban population has grown, development projects have encroached on wetlands, compromising their natural flood protection, air and water purification, and carbon storage capabilities. Additionally, hilly regions are at risk of landslides, particularly during the monsoon season, posing significant threats to vulnerable communities (4).
To address these challenges, the World Bank and the Sri Lankan government collaborated on the Metro Colombo Urban Development Project. This initiative focused on nature-based solutions (NBS) as cost-effective and sustainable approaches to risk management (4). By strengthening natural processes and ecosystem services, the project aimed to mitigate hazards such as floods, erosion, and landslides (4). Technical assessments by the World Bank highlighted the importance of wetlands in flood protection, leading to efforts to protect and restore 20 square kilometres of freshwater lakes, wetlands, and swamps (1, 4).
The project supported the Sri Lankan government in reducing flooding in the Colombo Water Basin and enhanced local authorities' capacity to manage infrastructure and services. It prioritised metropolitan investments to mitigate the physical and socioeconomic impacts of flooding and aimed to build long-term capacity for urban management and local service delivery (6).

The Urban Center of Good Initiatives (CUIB), a social enterprise launched by the NGO Mai Bine in 2013, is designed to drive social economies and support sustainable development in Iasi. The enterprise operates a bistro that promotes social consumption by supporting local producers, adhering to slow food principles through the use of local and seasonal ingredients, minimizing food waste, and encouraging sustainable transportation, among other eco-friendly activities (2 & 4).
In 2020, CUIB and Mai Bine joined the FoodE program, a European research and social project focused on local agri-food systems. Funded by the EU’s Horizon 2020 Framework Programme for Research and Innovation (2014-2020), the initiative empowered grassroots organizations through co-creation and collaboration among diverse stakeholders (5).
The FoodE project strengthened CUIB’s mission to provide low-carbon-impact food, promote ecological, ethical, and artisanal products, offer solidarity services such as free meals for the most vulnerable, engage in low-waste operations, provide education on mental and human ecology, and foster community through social and cultural events (1, p. 98). To further these goals, CUIB organized co-design workshops with 100 community members, focusing on achieving zero food miles, zero waste, and eliminating food waste (1, p. 99).
The program also led to improvements at the bistro, including the creation of a courtyard garden, a small terrace garden, along with a community garden (1, p. 100). These gardens supplied food to the bistro, and bio-waste was composted to fertilize the plots (1, p. 102). CUIB also hosted 17 outreach events as part of the initiative, including ecological workshops and the creation of a vegetable garden at a local kindergarten (3, p. 114 & 6).
Beyond its environmental work, CUIB provides free meals for 100 beneficiaries and organizes food donations for 400 vulnerable children and individuals (1, p. 103).

Located in the municipality of Morne Rouge, the Domaine d’Émeraude was once an agricultural site but was transferred to the Martinique Regional Natural Park (PNRM) in the early 2000s. It underwent significant renovations in 2005 to transform it into a sanctuary for Martinican biodiversity, reflecting the need to protect and conserve the island's unique ecosystems. In 2011, it opened its doors to the public, serving as an important educational resource that raises awareness about the island's historical, natural, and cultural heritage (Refs 4, 7, 8).
Today, the site encompasses 25 hectares protected from anthropogenic pressures and is primarily characterized by a humid tropical forest environment, which makes up 80% of the area (Ref 7). It is home to over a hundred native species (Ref 4) and offers nearly 4 kilometers of walking trails accessible to both adults and children, complete with recreational stops and educational amenities.
The Domaine d’Émeraude was designed to enhance the conservation of native species while developing sustainable economic activities that benefit the local community. Moreover, the site emphasizes the well-being that forested areas provide to visitors, highlighting that "the air can be heard, the smells can be savored, and the sounds can be experienced. The freshness of the place is a source of change and relaxation..." (Ref 4).

The "Ventanilla Wetlands" Regional Conservation Area (ACR) is an area of 275.45 hectares protected and administered by the Regional Management of Natural Resources and Environmental Management of the Regional Government of Callao (1, 2). It was established on December 20, 2006, by Supreme Decree No. 074-2006-AG, to conserve a representative sample of the coastal wetlands of the Subtropical Pacific Desert (2). With an ecosystem shaped by various hydrological and ecological processes, the "Ventanilla Wetlands" ACR is home to 126 bird species and 27 native plant species, making it an ideal area for ecotourism, recreational, educational, scientific, and cultural activities, thanks to its landscapes and biodiversity (2). However, the Ventanilla Wetlands face several challenges due to urban growth, water pollution, waste, traffic and plane overflights from the National Police and Navy, leading to a decline in bird populations due to noise exposure (5).
This area is fed by the hydrological system of the Chillón River, by surface waters from the Sedapal oxidation ponds, and by water seepage from nearby human settlements and populations adjacent to the wetland. The Ventanilla Wetlands are also influenced by the marine system, especially in the northwest zone. This gives the ACR area lagoon-like characteristics, meaning that its waters are slightly brackish despite being separated from the sea. The internal hydrological system supports the growth of species such as cattails, bulrushes, and reeds. In total, there are 27 native plant species, which serve the function of filtering and purifying the wetland's water. Additionally, the flora provides protection and food for various fauna species, particularly birds, with 126 species recorded, including resident and migratory birds from the Andes, local areas, and the Northern and Southern Hemispheres. Moreover, this protected natural area is home to five reptile species, including endemic species from Lima that are endangered (3).

The Kikås dump is a landfill in Mölndal, south of Gothenburg, where an area has been permanently covered with a sealing layer and inert material. This project aimed to utilise the area to increase biodiversity by establishing flowering meadows and an insect hotel, creating a habitat for wild bees, butterflies and birds [Ref. 1-3]. The City of Mölndal initated the project and sowed meadow flowers, established sand beds for burrowing insects, an uneven, rocky terrain and a large insect hotel [Ref. 1, 3]. The area is also meant to be a destination for recreation and learning about biodiversity. The Insect Hotel is marketed as the largest in Sweden, and it includes information signs and an outdoor classroom. The project is meant to raise awareness about biodiversity and ecosystem services such as pollination [Ref. 1, 4-6]. The area borders natural areas such as forests and wetlands and is meant to have positive ecological effects in the border zones. The project will contribute to the environmental goals of the city, in particular, "a rich plant and animal life" [Ref. 3]

The schoolyard at Reginhard Primary School in Reinickendorf faced persistent challenges, often becoming unusable due to poor drainage. After rainfall, water would pool, leaving the yard submerged and inaccessible to the 400 primary school pupils. Even in dry weather, the schoolyard was far from ideal: a lack of play equipment made it uninviting, and in summer, the area became excessively hot, offering little comfort or shade. Both children and the school community, including teaching staff and parents, voiced a strong desire for improvement.
Adding to the urgency for redesign, Berliner Wasserbetriebe imposed a discharge restriction, requiring rainwater to be managed on-site. This led to a comprehensive transformation of the school grounds. Large areas were unsealed, allowing water to seep naturally into the ground. Underground seepage systems were installed to enhance drainage, and the redesign introduced green spaces, a school garden, and near-natural play and exercise areas. These changes not only resolved the flooding issue but also created a more inviting and sustainable environment for students.
The focus on ecological and sustainable design improved the microclimate, providing cooler surroundings and enabling outdoor breaks filled with activity and fresh air. The redesign transformed the schoolyard into a vibrant space that meets the needs of both children and the environment.
This project was funded by the Berlin Programme for Sustainable Development (BENE Umwelt) and financed by the European Regional Development Fund (ERDF). (Ref. 3; Ref. 4)
